BioShock Infinite sells more than 4 million since March

Four million isn't Call of Duty numbers, but it's not half bad for a semi-political, semi-historical shooter: Take-Two Interactive CEO Strauss Zelnick shed some insight on BioShock Infinite's sales since March in a conference call with investors today (via Joystiq).

"BioShock Infinite is North America's best-selling multiplatform release so far this year, according to NPD," Zelnick said. "The title has crossed the 4 million units selling mark, and we expect it to become the top-selling release in the BioShock franchise."

Earlier today, BioShock Infinite fans got some more good news when three new pieces of DLC were revealed: arena-fighting Clash in the Clouds, which launches today, and Burial at Sea, a two-part narrative through Rapture starring familiar faces from both storylines.

Take-Two reported $142.7 million in net revenues for the three month period which ended on June 30, compared to $226.1 million for the same period of 2013. Its profit grew to $48.8 million from $39.4 million.
